The following information (Health Effects, Handling/Disposal, and Ingredients) is taken from the product label and/or the Material Safety Data Sheet (MSDS) prepared by the manufacturer. The National Library of Medicine does not test products nor does it evaluate information from the product label or the MSDS. (What is an MSDS?)

Health Effects

Acute Health Effects:

From MSDS
Emergency Overview
Exposure to dust may be irritating to eyes, nose, and throat.
Potential Acute Health Effects
Inhalation: Dusts and fibers from this product may cause mechanical irritation of the nose, throat, and respiratory tract.
Skin Contact: Dusts and fibers from this product may cause temporary mechanical irritation to the skin.
Eye Contact: Dusts and fibers from this product may cause temporary mechanical irritation to the eyes.
Ingestion: Ingestion of this product is unlikely. However, ingestion of product may produce gastrointestinal irritation and disturbances.

Medical Conditions Aggravated by Exposure: Chronic respiratory or skin conditions may temporarily worsen from exposure to this product.

Chronic Health Effects:

From MSDS
Chronic respiratory or skin conditions may temporarily worsen from exposure to these products.

Carcinogenicity:

From MSDS
In October 2001, the International Agency for Research on Cancer (IARC) classified fiber glass wool as Group 3, not classifiable as to its carcinogenicity to humans. The 2001 decision was based on human studies and animal research that have not shown an association between inhalation exposure to dust from fiber glass wool and the development of respiratory disease. This classification replaces the IARC finding in 1987 of a Group B designation-possibly carcinogenic to humans.
In May 1997, the American Conference of Governmental Industrial Hygienists (ACGIH) adopted an A3 carcinogen classification for glass wool fibers. The ACGIH A3 classification considers glass wool to be carcinogenic in experimental animals at relatively high doses, by routes of administration, at sites, or by mechanisms that it does not consider relevant to worker exposure. It also reviewed the available epidemiological studies and concluded that they do not confirm an increased risk of cancer in exposed humans. Overall, the ACGIH found that the available medical/scientific evidence suggests that glass wool is not likely to cause cancer in humans except under uncommon or unlikely routes or levels of exposure.

In 1994, the National Toxicology Program (NTP) classified glass wool (respirable size) as reasonably anticipated to be a human carcinogen. This classification was primarily based upon the 1987 IARC classification. NTP is currently considering reclassifying this material.

First Aid:

From MSDS
Inhalation: If inhaled, remove the affected person to fresh air. If irritation persists get medical attention.
Skin Contact: For skin contact, wash with mild soap and running water. Use a washcloth to help remove fibers. To avoid further irritation, do not rub or scratch affected areas. Rubbing or scratching may force fibers into the skin. If irritation persists get medical attention. Never use compressed air to remove fibers from the skin. If fibers are seen penetrating from the skin, the fibers can be removed by applying and removing adhesive tape so that the fibers adhere to the tape and are pulled out of the skin.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes. If irritation persists get medical attention.
Ingestion: Ingestion of this material is unlikely. If it does occur, watch the person for several days to make sure that partial or complete intestinal obstruction does not occur. Do not induce vomiting unless directed to do so by medical personnel.

From MSDS
Handling Procedures: Keep product in its packaging until use to minimize potential dust generation. Keep work areas clean. Avoid unnecessary handling of scrap material. Follow good industrial hygiene practices when handling this material.
Storage Procedures: Material should be kept dry and undercover.

Disposal:

From MSDS
Material, if discarded, is not expected to be a characteristic hazardous waste under RCRA. Dispose of waste material according to Local, State, Federal, and Provincial Environmental Regulations.
